UNITED STATES ATENT OFFICE JOSEPH MURPHIN, OF MALAGA, NEW JERSEY, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO ALFRED B. RIOHMAN, OF SAME PLACE.

FRUIT-JAR.

SPECIFICATION forming part of Letters Patent No. 233,792, dated October 26, 1880.

Application filed September 14, 1880. (No model.)

To all whom it may concern Be it known that I, JOSEPH MURPHIN, a citizen of the United States, residing in Malaga, Gloucester county, New Jersey, have invented an Improvementin Fruit-Jars, of which the following is a specification.

The object of my invention is to provide a simple and inexpensive means whereby the cover of a fruit-jar can be firmly clamped to the body and a tight joint between the two insured without interfering with the ready removal of the cover, when desired. This object I attain in the manner which I will now proceed to describe, reference being had to the accom- I 5 panying drawings, in which Figure 1 is a Vertical section of the upper portion of a fruit-jar having a cover secured thereto according to my invention; Fig. 2, a side View of the same, and Fig. 3 a perspec- 2o tive view of one of the clamping-staples.

A is the body of the jar, on the neck of which, below the mouth, is formed a shoulder, a, for the gasket 1), and beneath said shoulder a are formed inclined shoulders (I d, with which engage the hooked lower ends, 6, of clampingstaples B, each of which consistsof a bar of metal bent at right angles, the horizontal portion f of each staple bearin g upon thetop of the cover D and having a hook, g, which engages 0 with an annular shoulder, m, formed on the top of said cover.

At the shallow end of each inclined shoulder (1 is a recess, n, and when the lid has been properly applied to the jar the clamping-sta- 5 ples are adapted thereto, the hook g of each staple being first applied to the rib m of the lid, and the hook e of the staple then slipped laterally into one of the recesses on prior to the movement of the staples in the direction of the arrows, so that the engagement of the hooks c with the inclined shoulders d will effectually clamp the lid to the jar and insure a tight joint by pressure on the gasket b. If desired, a single gasket, 2), only may be used;

5 but in some cases it is preferable to recess the lid D for the reception of a supplementary gasket, I), which bears upon the projecting upper edge or mouth of the jar.

When it is desired to detach the cover D the staples B must be retracted until their hooks 5o 0 occupy the recesses a and are free from the shoulders d, the engagement of the hooks c with said shoulders otherwise preventing the detaching of the hooks g from the shoulder m of the cover D.

By making a plain annular rib or shoulder on the cover and inclined shoulders on the neck of the jar. I am enabled to make a better fit of the parts than if the inclined shoulders are formed on the cover, because in the latter case the shoulders have a tendency to Warp during the annealing operation, and thus interfere with the proper action of the clamping-staples.

As the clamping-staples are independent of each other in their action, slight differences in the character of the shoulders at will not affeet the secure clamping of the cover as they would if the said cover were confined by a clamping-yoke acted upon by both shoulders simultaneously.

The staples are simple and inexpensive, and can be readily applied or removed. Moreover, as they do not extend across the cover D, they do not interfere with the use of an air-pump for exhausting the air from the jar.

I claim as my invention The combination of the jar A, having inclined shoulders d d on the neck, below the mouth, the cover D, having a vertical shoul- 8o der, m, and the independent clamping-staples B, each having a hook, e, engaging with one of the shoulders 01 on the jar, and a hook, g, engaging with the shoulder m on the cover, as set forth. 8 5

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH MURPHIN.
